Perhaps you should try some spelling variations:
thuat sach » thuat san
thuat lanh » thuat lap, thuat san
hanh vai » hanh vi, hanh va, hanh tai
cau loc » hau loc, cau hoc, cau long
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
cau luc » cau truc, cau phuc
cua tre » cua te, cuu tre, cua triet
ly nang » ky nang, ly hang, ly vang
hieu ve » hieu va, hieu van
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (thuat lanh)) ly nang x hoi. hieu ve ((cau loc) OR (cau luc)) va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) OR (thuat lanh)) ly nang x hoi. hieu ve ((cau loc) or (cau luc)) va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) OR (thuat lanh)) ly nang x hoi. hieu ve ((cau loc) or (cau luc)) va hanh vai cua tre*.
